I purchased the hp22i insert pellet stove only 3 years ago and it worked good for one winter, then problems. The second winter the augur bearings had issues, now in the third season it is not working at all. I had to pull the unit out of its inserted position, take apart the trim...which is a complete paine and go through all the trouble shooting steps to figure why the exaust fan isn't circulating. So far no luck. For $2500+ I expected a better product,one that would be working fine 3 yrs in, but like the old timers say, "they don't make stuff like they used to." I don't reccomend this stove.
